11.4 Images and Tables

Both the native Org mode tables (see Tables) and tables formatted with
the table.el package will be exported properly. For Org mode tables,
the lines before the first horizontal separator line will become table header
lines. You can use the following lines somewhere before the table to assign
a caption and a label for cross references, and in the text you can refer to
the object with [[tab:basic-data]] (see Internal links):

#+CAPTION: This is the caption for the next table (or link)
#+NAME: tab:basic-data
| ... | ...|
|-----|----|

Optionally, the caption can take the form:

#+CAPTION[Caption for list of tables]: Caption for table.

Some back-ends allow you to directly include images into the exported
document. Org does this, if a link to an image files does not have
a description part, for example [[./img/a.jpg]]. If you wish to
define a caption for the image and maybe a label for internal cross
references, make sure that the link is on a line by itself and precede it
with #+CAPTION and #+NAME as follows:

#+CAPTION: This is the caption for the next figure link (or table)
#+NAME: fig:SED-HR4049
[[./img/a.jpg]]

Even though images and tables are prominent examples of captioned structures,
the same caption mechanism can apply to many others (e.g., LaTeX
equations, source code blocks). Depending on the export back-end, those may
or may not be handled.
